It's important to note that associated corporations are taken into account when determining eligibility for the small business deduction.

Differentiating Between Tax Deductions, Credits, and Write-Offs

Understanding the difference between tax deductions, tax credits, and tax write-offs is crucial for managing your business's tax liability and optimizing your tax savings. Let's briefly differentiate between these concepts:

  • Tax Deductions/Write-Offs: Tax deductions/write-offs reduce your taxable income, which in turn lowers your tax liability. They are expenses incurred in the course of running your business that can be subtracted from your taxable income.

  • Tax Credits: Tax credits directly reduce the amount of taxes you owe. They are applied after calculating your tax liability and can result in a dollar-for-dollar reduction in your tax bill.
